I have studied all the great information on the forum related to turning the rear Volt reflectors into lights. I tried the "take them apart and add LEDs" method - one reflector came apart so easily I wondered what all the fuss was about. The other one, which was bought at the same time, was impossible to split apart - the glue refused to budge, even at elevated temperature (240 degrees!). I actually ended up melting the plastic, and it STILL wouldn't come apart.

So, now I am thinking about drilling a couple of holes in the back of the reflector and adding 10mm Superbright red LEDs to illuminate the reflectors. I read where someone was trying this, but I haven't heard how, or if, it worked, and how well it worked. I would want the rear reflectors to match the brightness of the corner tail lights. They will operate as running lights and brake lights.

The challenge I am having in researching / designing the discrete LED method has to do with the 20 - 30 degree view angle of most LEDs (I found some that are 40 degrees) and how to arrange them in the reflector so the whole thing illuminates evenly. 1.) Behind the black center mask, pointed sideways? 2.) At the edges, both sides, pointing towards the center (sideways)? 3.) Something else?

Any advice / experience would be appreciated! Thanks!

Best Regards,

Incandescent would have a more even fill. And it would match the factory tail lights.

That does help - thank you. The 7443 lamp would be the obvious one to use for the rear reflectors, just have to find a way to fit it to the reflector and the hatch lid. I am researching the 7443 and also the 67 bulb, which is available in LED, but had 4 bright "sideways" LEDs which may act to illuminate the whole reflector area. I have ordered some and will be doing testing soon.

Best Regards,

Check out what Anthony Vigil has done on the FB Volt Owners group.
He was even selling LED modified reflectors, but don't see them there any more.

Yes, I have read all of his posts, and even tried contacting him via e-mail, but I got no response. He was talking about another version with 10mm LEDs entering from the back, but I never heard if he tried it, or what the results were.

Best Regards,

I tried the posterior heat approach in my 3 yrs old reflectors, with multiple linear cracks in the clear glass, had to use NITE-SHADE to darken the red glass with reasonable final result covering the cracks... I agree the posterior approach drilling the black plastic is safer, WEST MARINE has DRLED bulbs... a pain in the neck project but once finished is worth it. Good luck.
